Madden-Julian Oscillation (MJO) Research at PSD

The MJO is a mode of sub-seasonal atmospheric variability that influences the location and strength of tropical precipitation. It moves eastwards through the atmosphere and its effects are visible over the warm parts of the Indian and Pacific oceans. It takes the MJO about 30-70 days to travel around the equator.
It can interact with other tropical phenomena including ENSO and the Indian Monsoon and it impacts precipitation in mid-latitudes.
Scientists are currently studying the processes involved in the MJO, MJO impacts and how to better model it in "General Circulation Models (GCMs)".
